IRT Observed-Score Kernel Equating with the R Package kequate

The R package kequate enables observed-score equating using the kernel method of test equating. We present the recent developments of kequate, which provide additional support for item-response theory observed score equating using 2-PL and 3-PL models in the equivalent groups design and non-equivalent groups with anchor test design using chain equating. The implementation also allows for local ...

Are Measures of Character and Personality Distinct? Evidence From Observed-Score and True-Score Analyses.

Two studies were conducted to investigate redundancy between the character strengths found in the VIA model of character and familiar personality facets. Study 1 used a community sample ( N = 606) that completed a measure of character strengths, four personality inventories, and 17 criterion measures. The second study used Mechanical Turk workers ( N = 498) who completed measures of the HEXACO ...

Marginal True-Score Measures and Reliability for Binary Items as a Function of Their IRT Parameters

This article provides analytic evaluations of population true-score measures for binary items given their item response theory (IRT) calibration. Under the assumption of normal trait distribution, the expected values of marginalized true scores, error variance, true score variance, and reliability for norm-referenced and criterion-referenced interpretations are presented as a function of the it...

Standard Error Estimation of 3PL IRT True Score Equating With an MCMCMethod

A Markov chain Monte Carlo (MCMC) method and a bootstrap method were compared in the estimation of standard errors of item response theory (IRT) true score equating. Three test form relationships were examined: parallel, tauequivalent, and congeneric. Data were simulated based on Reading Comprehension and Vocabulary tests of the Iowa Tests of Basic Skills1. For parallel and congeneric test form...

A comparison of Van der Linden's conditional equipercentile equating method with other equating methods under the random groups design

To ensure test security and fairness, alternative forms of the same test are administered in practice. However, alternative forms of the same test generally do not have the same test difficulty level, even though alternative test forms are designed to be as parallel as possible. Equating adjusts for differences in difficulties among forms of the test. Six traditional equating methods are consid...
